`@RATE FOR STOVES.

SPECIFICATION formingpart of Letters Patent No. 249,205, dated November 8, 1881. Application filed August t), 1881. (No model.)

To all whom t may concern: y

Be itknown that I,HENRY M. RYDER, of Taunton, in the couniyof Bristol and State of Massachusetts, have invented an improved 5 Gratefor Stoves,Ranges, and the like, ot' which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, in which .Figure'l is a plan. Fig. 2 is a section on io line x x. Fig. 3 is a section on line y y. Figs. 4 and 5 are end views.

My invention relates to mechanism for shaking the grate; and it consists in means for causing thcvibration ofthe grate-bars and in connecting the grate-bars together so that the oscillation of one will cause all the others connected with it to oscillate.

In.the drawings I have shown the best'form of grate known to me and embodying my inzo vention.

A is the bed-plate, in which the grate-frame B is supported upon the journals b b', one of which, b', projects through the stove,V so that a suitable wrench may be applied for dumping the grate, as will be clear without further description.

In order that a suitable wrench may heapplied to one oi" the grate-bars, F', to oscillate it on its journalsff, thejournalf is elongated,

3o as shown more clearly in Figs. l and 2, the extremity f2 of the elongationf' -being squared to receive the Wrench. Each grate bar is mounted on journals ff in the grate-frame B, and each has a finger, f3, on it. These ngers enter holes in a rod, f4, and consequently the grate-bars are connected together by thisrod f4 and the fingers f3, so that when bar F is oscillated all the others will oscillate with it.

The grate-frame is best cast in three parts,

This is in order that the jonrnalsff of the grate-bars F F' may be laid in the half-boxes in the lower cross-pieces b2 b3 and secured in place by letting in the upper cross-pieces, b5 bfi. The connecting-pieces b4 also serve as asupiport for 45 the rodf The projection f5 on rodj'4 servesy as a stop to limit the reciprocating motion ot' rodft, and consequently to limit the degree of oscillation of the, grate-bars, for when gratebar Fl is turned on itsjournals ff/ by the 5o Wrench the tlngerj"3 will slide rod fL endwise until the projectionj'5 comes 'against one of the connectingpieces b4, as will be clear from Figs. 2, 3, and 4.

A minor feature of my invention consists in making journal b hollow and oscillating the grate-bar F' through it, the advantage being that only the usual opening through the stove is required, for it is obvious that it' `any other of the grate-bars `avere oscillated, except the 6o one Whose axis is substantially coincident With the axis ot'thejonrnals b b', two openings would be necessary, one for a projection from the Wrench to take hold ot one of the grate-bars (corresponding to elongation f) and the other for the journal b.

Although l have describe-d my invention as applied only to a stove, it is clear that it is applicable not only to stoves and the like, but may be desirable in other cases.

What l claim as my invention isl. In a grate, the bars F F', jonrnaled respectively, at j' j" in the grateframe, and connected together by iingers f3 and rod f4, the bar F having the elongation f2 for oscillating 75 it, all combined together substantially as described.

2. The grateframe B, journaled at b b, the grate-bars F F", journaled respectively at fj" in the grateframq and connected together by 8o ngersj'3 and rodft, the elongation f2 of bar F' passing through the hollow journal b' of frame B, all combined together as set forth.

HENRY M. RYDER.
